Hazard Predictions

• Flammable: Reaction products may be flammable
• Generates heat: Exothermic reaction at ambient temperatures (releases heat)
• Intense or explosive reaction: Reaction may be particularly intense, violent, or explosive

Mixtures of powdered electropositive metals (such as aluminum, magnesium, titanium, zinc, or zirconium) with certain metal oxides (such as those of iron, barium, chromium, cobalt, copper, manganese, molybdenum, lead, vanadium, nickel, or silicon) react explosively and at extremely high temperatures once ignited. These mixtures are called thermites (P. J. Roebuck, Educ. Chem., 1979, 16, 178-9; G. V. Ivanov, et al., Chem. Abs., 1979, 91, 76323; M. B. Ismailov, et al., Fizika Goreniya i Vzryva, 1992, 28(1), 46; J. W. Mellor, 1961. Mellor's Comprehensive Treatise on Inorganic and Theoretical Chemistry. Vol. 7, pp. 20. Longmans, Green and Co Ltd.; J. W. Mellor, 1940. Mellor's Comprehensive Treatise on Inorganic and Theoretical Chemistry. Vol. 4, pp. 272. Longmans, Green and Co Ltd.; J. R. Partington, 1967, General and Inorganic Chemistry, London, MacMillan, 4th ed., p. 364; Pascal, P. 1958. Nouveau Trait茅 de Chimie Min茅rale. Vol. 4, p. 775. Masson et Cie.).

Neutral solutions of salts of heavy metals such as nickel, iron, and copper are corrosive to magnesium alloys. The metals in the salts are reduced, and the resulting powders can be pyrophoric (Aune, T. K., et al. 2003. Magnesium Alloys. Ullmann's Encyclopedia of Industrial Chemistry. (Online)).

Zinc can ignite on contact with ammonium chloride, if water is present (G. Sorbe, 1968, Giftige und Explosive Substanzen, Frankfurt, Umschau Verlag, pp. 158; Hanson, R.M. 1976. Journal of Chemical Education 53:578).

Aluminum can react violently with AgCl if the silver chloride is in excess (Anon. 1954. Chemical and Engineering News 32:258; J. W. Mellor, 1946. Mellor's Comprehensive Treatise on Inorganic and Theoretical Chemistry. Vol. 3, pp. 402. Longmans, Green and Co Ltd.).
